Slack is experiencing some connectivity issues — please stand by. Check
* We're no longer updating the Slack app for Windows Phone as of June 14, 2018.
Connect to Slack from the web on your desktop anytime at slack.com/signin — just make sure you're using one of our supported browsers.
Coming soon: Starting on March 15, 2019, we are changing the minimum browser requirements needed to run Slack. Please make sure your browser is up to date.
Requirements (March 15, 2019)
Version 51 and newer
Version 66 and above
Version 47 and newer, plus version 45 (ESR)
Version 60 and above
9 and newer
10.1 and above
Version 31 and newer
Version 41 and above
No longer supported
Unsupported browsers and OS
To focus on delivering the best possible experience in Slack, it is necessary to keep the list of supported browsers and operating systems short.
When a browser is no longer supported, we stop fixing pesky bugs and issues. For a customer, that could be a terrible Slack experience! We do our best to avoid that scenario by blocking unsupported browsers from accessing Slack.
